{"version":"1.0","type":"rich","title":"choropleph with interactive filtering","description":"This choropleth map displays world countries colored by economy category, with an accompanying ordinal color legend. Clicking a legend category filters the map by fading non-matching countries to low opacity and highlighting the selected group. Built with D3 v5, it uses `geoNaturalEarth1` and `geoPath` for projection, `scaleOrdinal` with `schemeSpectral` for colors, and `zoom` for panning. Data comes from the World Atlas TopoJSON and TSV files, rendered as SVG paths.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/9b37f91c883e4693958f3092225f3762?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
